Abstract
Methods and apparatuses are provided for wireless communication. Control symbols are mapped to a plurality of resource element groups (REGs) which is not assigned to a physical channel format indication channel (PCFICH) or a physical hybrid automatic repeat request indicator channel (PHICH). The REGs are allocated based on a time first manner. The mapped control symbols are transmitted on a packet dedicated control channel (PDCCH).
Claims20
A method for wireless communication, the method comprising:
- mapping control symbols to a plurality of resource element groups (REGs) which is not assigned to a physical channel format indication channel (PCFICH) or a physical hybrid automatic repeat request indicator channel (PHICH), the REGs being allocated based on a time first manner and four symbols being mapped to a plurality of resource elements (REs) in each of the REGs;
- and
- transmitting the mapped control symbols on a packet dedicated control channel (PDCCH),
- wherein an REG is represented by a frequency index and a time index of a first RE among the plurality of REs in the REG having the same time index, and
- wherein mapping control symbols is skipped if an RE in the REG is not the first RE.
An apparatus for wireless communication, the apparatus comprising:
- a controller configured to control operations of:
- mapping control symbols to a plurality of resource element groups (REGs) which is not assigned to a physical channel format indication channel (PCFICH) or a physical hybrid automatic repeat request indicator channel (PHICH), wherein the REGs are allocated based on a time first manner and four symbols being mapped to a plurality of resource elements (REs) in each of the REGs;
- and
- transmitting the mapped control symbols on a physical channel format indication channel (PDCCH);
- and
- a transmitter configured to transmit the mapped control symbols on the PDCCH,
- wherein an REG is represented by a frequency index and a time index of a first RE among the plurality of REs in the REG having the same time index, and
- wherein mapping control symbols is skipped if an RE in the REG is not the first RE.
A method for wireless communication, the method comprising:
- receiving a control signal on a physical channel format indication channel (PDCCH);
- and
- obtaining control symbols mapped to a plurality of resource element groups (REGs) from the received control signal, wherein the REG is not assigned to a physical channel format indication channel (PCFICH) or a physical hybrid automatic repeat request indicator channel (PHICH) and is allocated based on a time first manner, and four symbols being mapped to a plurality of resource elements (REs) in each of the REGs,
- wherein a REG is represented by a frequency index and a time index of a first RE among the plurality of REs in the REG having the same time index, and
- wherein mapping control symbols is skipped if an RE in the REG is not the first RE.
An apparatus for wireless communication, the apparatus comprising:
- a receiver configured to receive a control signal on a physical channel format indication channel (PDCCH);
- and
- a controller configured to control operations of:
- obtaining control symbols mapped to resource element groups (REGs) from the received control signal, wherein the REG is not assigned to a physical channel format indication channel (PCFICH) or a physical hybrid automatic repeat request indicator channel (PHICH) and is allocated based on a time first manner, and four symbols being mapped to a plurality of resource elements (REs) in each of the REGs,
- wherein an REG is represented by a frequency index and a time index of a first RE among the plurality of REs in the REG having the same time index, and
- wherein mapping control symbols is skipped if an RE in the REG is not the first RE.
